Description

Engine power turbine power recovering device
Technical field
The utility model relates to engine art, particularly a kind of engine power turbine power recovering device.
Background technique
Available engine power turbine energy recycle device mainly comprises power turbine and clutch mechanism, and power turbine is mechanical work drives external loading by clutch mechanism a turbomachine with the engine exhaust Conversion of energy.Power turbine is installed in the turbosupercharger rear portion, connects with turbosupercharger.Engine exhaust at first passes through turbosupercharger, the part discarded energy is recycled by turbosupercharger, the turbine end that remaining exhaust energy then enters power turbine, the rotation of promotion turbine, the rotation of turbine drives one and the work of crankshaft gear oncoming clutch mechanism, promotes crankshaft rotating and output power.
But when the exhaust energy utilization ratio was low, clutch mechanism kept separated state, and causing power turbine can not be the output work of bent axle with the engine exhaust Conversion of energy; When having only the exhaust energy utilization ratio high, this clutch just engages, power turbine could be the output work of bent axle with the engine exhaust Conversion of energy, therefore, engine power turbine power recovering device only the part operating mode just work and frictional loss big, cause the exhaust energy utilization ratio low, and this engine power turbine power recovering device complex structure, parts are many, the cost height, because clutch mechanism weight is big, be unfavorable for the lightweight of motor in addition.
The model utility content
The utility model is in order to overcome defective in the above-mentioned prior art, to provide a kind of simple and reasonable, exhaust energy utilization ratio height, and cost is low, and is beneficial to the light-weighted engine power turbine power of motor recovering device.
For achieving the above object, provide a kind of engine power turbine power recovering device according to the utility model, having comprised: first turbine and generator, first turbine is connected on the turbosupercharger rear portion, and be connected the generator power supply that links to each other with motor storage battery or circuitry with generator drive.
In the technique scheme, turbosupercharger comprises: second turbine and gas compressor.
In the technique scheme, after cooling off through intercooler, the inlet air after the gas compressor supercharging enters combustion system of engine and fuel mix burning.
Compared with prior art, the utlity model has following beneficial effect: this engine power turbine power recovering device adopts the power turbine of band generator, power turbine directly drives generator for electricity generation, the electric energy that generator sends can be stored in the storage battery, also can be directly used in the circuitry on motor or the car load, omitted complicated clutch mechanism, make that this engine power turbine power recovering device is simple and reasonable, exhaust energy utilization ratio height, cost is low, and is beneficial to the motor lightweight.

The 1-turbine, 2-generator, 3-motor, 4-turbine, 5-gas compressor, 6-intercooler.
Embodiment
Below in conjunction with accompanying drawing, an embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model is not subjected to the restriction of embodiment.It will be appreciated that, mentioned in the following mode of execution of the present utility model " on ", D score, " left side ", " right side ", " front " and " reverse side " be benchmark with the direction shown in each figure all, these words that are used for limiting direction only are for convenience of explanation, do not represent the restriction to the concrete technological scheme of the utility model.
Engine power turbine power recovering device of the present utility model adopts the power turbine of band generator, power turbine directly drives generator for electricity generation, the electric energy that generator sends can be stored in the storage battery, also can be directly used in the circuitry on motor or the car load, omitted complicated clutch mechanism, made that this engine power turbine power recovering device is simple and reasonable, exhaust energy utilization ratio height, cost is low, and is beneficial to the motor lightweight.
As shown in Figure 1, the concrete structure of this engine power turbine power recovering device comprises: turbine 1 and generator 2, turbine 1 drive with generator 2 and are connected, and the exhaust energy of motor 3 enters the turbine end of turbine 1, the rotation of promotion turbine, turbine drive generator 2 generatings again.
Turbine 1 is installed in engine turbine pressurized machine rear portion, connects with turbosupercharger.Turbosupercharger is actually a kind of air compressor, increases air inflow by pressurized air, mainly comprises: turbine 4 and gas compressor 5.It is that the waste gas inertia impulsive force that utilizes motor to discharge promotes the turbine 4 in the turbine chamber, drives the inlet air of gas compressor 5 compression engines again, makes it to burn with fuel mix by entering combustion system of engine after intercooler 6 coolings after the supercharging.When engine speed speeds, the waste gas velocity of discharge and secondary speed also speed synchronously, gas compressor 5 just compresses more air and enters cylinder, the pressure of air and density increase the more fuel that can burn, the rotating speed of corresponding increase fuel quantity and adjustment motor just can increase the output power of motor.
Motor 3 waste gas are through behind the turbine 4 of turbosupercharger, the part exhaust energy is recycled by turbosupercharger, the turbine end that remaining exhaust energy then enters turbine 1, the rotation of promotion turbine, the rotation of turbine drives generator 2 generatings, generator 2 is connected with the turbine of power turbine and links to each other with circuitry on storage battery or motor and the car load, and the electric energy that generator 2 sends can be stored in the storage battery, also can be directly used in the circuitry on motor or the car load.Because adopt a generator to replace the clutch mechanism of original complexity, this engine power turbine power recovering device is simple in structure, parts are few, and cost is low.As long as the diesel engine operation, generator just can be worked, and modern generator is converted to mechanical energy the efficient of electric energy up to more than 99%, compares high rotating speed operating mode work of having only of clutch and mechanical loss and is no less than 10% shortcoming, and the exhaust energy utilization ratio is higher; Generator is lighter than clutch configuration, uses the power turbine energy recycle device of band generator more to meet light-weighted demand.
To sum up, this engine power turbine power recovering device adopts the power turbine of band generator, power turbine directly drives generator for electricity generation, the electric energy that generator sends can be stored in the storage battery, also can be directly used in the circuitry on motor or the car load, has omitted complicated clutch mechanism, make that this engine power turbine power recovering device is simple and reasonable, exhaust energy utilization ratio height, cost is low, and is beneficial to the motor lightweight.
More than disclosed only be several specific embodiment of the present utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into protection domain of the present utility model.
